Meeting the environmental and energy challenges of a changing world.
The Pollutec fair in the French city of Lyon recently brought together more than 2,000 exhibitors from some 30 different countries presenting all the latest in green technology, to allow for more responsible industrial production, a reduced impact of our public services and better living conditions in our towns and cities.
“New projects presented this year obviously target the environmental and energy sectors,” said Pollutec’s new director, Stephanie Gay Torrente.
“Manufacturers are proposing more efficient and sustainable solutions aimed at sectors like waste management, water management, the production of renewable energy, risk management, air quality and sustainable development at large.”
French firm Armor presented an innovative, organic photovoltaic module, that converts any kind of light into electricity. Made of highly flexible material, it can be applied to different kinds of surfaces, a step forward compared to traditional solar panels.
“The novelty is that it’s a solar film, which transforms light into energy. Unlike a solar panel, which is heavy, at 8 kilos per square meter, and which has to be on a flat surface because of its rigidity, this one is supple, flexible and light. It only weighs a few hundred grams per square meter, which means you can put it on a curved surface, like a street lamp for example. It converts light into energy, without the need for any electric cables,” said solar technology expert Hubert de Boisredon.
The German company, Mennekes, introduced an innovative charging station for electric cars. Using a special ID card, motorists can charge up using their smartphone, which also provides statistics about the energy consumed. They can chose to recharge their vehicle at night, for example, when the cost of electricity is lower.
Most waste collection nowadays is subject to static routes and schedules. Containers are collected on a regular basis whether they are full or not, causing unnecessary costs. Finnish company Enevo has introduced ultrasound wireless sensors that gather fill level data from waste containers and send it to a cloud-based platform. The platform then generates smart collection plans using the most efficient schedules and routes – generating up to 50% savings according to its inventors.
French firm Ecobatec presented its innovative machine, which tests the state of a car battery in just a few seconds. A green light means your old battery is still good. A red light means it’s good for recycling. According to the firm, more than one in three car batteries can be reused, in public spaces like parkings or supermarkets for example.
And Water Rails is an easy-to-use flood protection barrier for water levels between 30 cm and 2 metres high. Very rapid to install, Water Rails is to be used as preventative action in the event of a flood warning.
“So how does it work?,” asked water flood expert Philippe Deliance. “Well, we have these tubes that are filled with air to begin with, and then filled with water, before they are piled up. You can wrap them round buildings or homes. So what we’re doing is we’re fighting water with water,” he concluded.
